Description

Technical Field

[0001] The invention relates to a device for fixing an electrolytic cell plate, in particular to a self-suspended conductive bar device for fixing an electrolytic cell plate. Background Art

[0002] In the ISA copper electrolytic refining process, cast copper of a specific shape serves as the anode, and a stainless steel cathode plate of a specific shape serves as the cathode. A specific number of anodes and cathodes are arranged within a specific electrolytic cell, spaced at regular intervals. Conductive bars are suspended from the upper sides of the cell, connecting the anodes and cathodes. A flowing acidic liquid serves as the electrolyte, and a constant current flows through the anode and cathode. The copper anodes continuously dissolve, and high-purity copper is adsorbed onto the stainless steel cathode plate. Other precious metals and impurities in the copper settle to the bottom of the cell, completing the electrolytic refining of the cathode copper.

[0003] Throughout the electrolytic refining process, it is crucial to maintain the same spacing between the anode and cathode plates. Different spacing can cause quality fluctuations and increased power consumption. However, as the anode plate continues to dissolve, its center of gravity can easily shift, causing changes in verticality. Meanwhile, the cathode plate can easily shift position as it absorbs high-purity copper. Consequently, significant variations in the spacing between the anode and cathode plates are common throughout the electrolytic refining process. To ensure that the anode and cathode plates are consistently spaced at the same distance, the existing method involves manual adjustment of each anode and cathode. This not only incurs significant labor costs but also compromises safety management, significantly impacting overall operational efficiency.

[0004] Therefore, the purpose of the present invention is to design a self-suspended conductive bar device for fixing the electrolytic cell plates that can automatically adjust the positions of the anode plates and cathode plates during the electrolytic refining process to ensure that the anode plates and cathode plates can be continuously kept at appropriate spacing conditions for electrolytic refining, thereby effectively improving the electrolytic refining efficiency and improving safety. Summary of the Invention

[0005] In response to the technical problems existing in the above-mentioned prior art, the present invention provides a self-suspended conductive bar device for fixing the electrolytic cell plates, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is: A self-suspended conductive bar device for fixing an electrolytic cell plate, comprising: A group of conductive bars are fixedly mounted on the upper portion of the crossbeams on both sides of the corresponding electrolytic cells, wherein a row of first conductive bumps and a row of second conductive bumps are arranged side by side on the conductive bars, wherein the top portions of the first conductive bumps are arranged in an upward convex arc shape, and the top portions of the second conductive bumps are arranged in an inward concave arc shape, and are staggered relative to the first conductive bumps; A set of insulating plates, respectively fixedly embedded between the first conductive protrusion and the second conductive protrusion of the conductive bar, with first and second insulating blocks respectively fixedly connected outwardly to both sides of the insulating plates and embedded in the sides of the first and second conductive protrusions, the top portion of the first insulating block being arranged in an inwardly concave arc shape, and the top portion of the second insulating block being arranged in an upwardly convex arc shape; A plurality of anode fixing ear plates are respectively fixed to the top of both sides of the corresponding anode plates, and the bottoms of the anode fixing ear plates are all arranged in a flat shape. The anode fixing ear plates on the same anode plate are respectively fixedly abutted against the top of the first conductive protrusion of one conductive row and the top of the second insulating block provided on the insulating plate of another conductive row; Multiple cathode fixing ear plates are respectively fixed to the top of both sides of the corresponding cathode plates. The bottoms of the cathode fixing ear plates are all arranged in a downward convex arc shape. The cathode fixing ear plates on the same cathode plate are respectively fixed to the bottom of the first insulating block on the insulating plate of one conductive row and the bottom of the second conductive protrusion of another conductive row.

[0007] Corresponding insulating rubber pads are respectively provided between the bottom of the conductive bar and the crossbeam of the electrolytic cell.

[0008] The conductive bar is made of pure copper, and the insulating plate is made of insulating resin.

[0009] The self-suspended conductive bar device further includes a multifunctional connection component, and the multifunctional connection component includes: The clip is provided in the shape of an elongated strip, and the cross section of the clip is a trapezoidal shape or an inverted T shape. The middle portion of the conductive bar is provided with a clip groove adapted to the shape of the clip, and the clip is fixedly inserted into the clip groove of the conductive bar; A plurality of tensioning rods are arranged side by side on the upper part of the clamping member. The tensioning rods are made of elastic steel and are arranged in an upper convex dome shape. The bottom of the tensioning rod is fixed to the clamping member. A corresponding receiving groove is provided downwardly in the middle part of the insulating plate. The top end of the tensioning rod is pressed against the top of the receiving groove to lift the insulating plate. The locking piece is used to buckle the insulating plate onto the conductive bar. After the bottom of the insulating plate abuts against the top of the conductive bar, the entire tightening rod is embedded in the accommodating groove of the insulating plate.

[0010] The locking member adopts an airbag arranged in a long strip shape, and the airbag is fixedly sleeved inside the multiple tightening rods and fixed to the top end of the tightening rods; when the airbag is inflated, the tightening rods are expanded laterally, so that the airbag and the tightening rods are embedded in the accommodating groove as a whole, so as to drive the insulating plate downward to abut against the upper side of the conductive bar; when the airbag is depressurized, the tightening rods restore their deformation to lift the insulating plate.

[0011] The clamping groove and the accommodating groove are provided with a clearance groove for clamping the tightening rod.

[0012] The cross section of the accommodating groove is 3 / 4 circular.

[0013] The end of the air bag is provided with an air nozzle for inflating or relieving pressure.

[0014] Advantages of the present invention: 1) This invention improves the structure of the conductive bars and insulating plates. By coordinating the first and second conductive bumps on the conductive bars, and the first and second insulating blocks on the insulating plates, the anode fixing lugs on the same anode plate are fixedly abutted against the top of the first conductive bump on one conductive bar and the top of the second insulating block on the insulating plate of the other conductive bar. Meanwhile, the cathode fixing lugs on the same cathode plate are fixedly abutted against the bottom of the first insulating block on the insulating plate of one conductive bar and the bottom of the second conductive bump on the insulating plate of the other conductive bar. This achieves single-sided staggered conduction and insulation between adjacent anode and cathode plates, facilitating the smooth progress of the electrolytic refining process.

[0015] The anode fixing lug forms line contact with the upwardly convex first conductive protrusion and the second insulating block. Under the action of the anode plate's own weight, it can suspend itself, thereby automatically correcting the anode plate's verticality during the dissolution process. The cathode fixing lug forms arcuate contact with the inwardly concave first insulating block and the second conductive protrusion. Under the action of its own weight, it not only achieves the self-suspending function, but also automatically guides the cathode fixing lug, i.e., the cathode plate, between the bottommost parts of the first insulating block and the second conductive protrusion, thereby automatically correcting the verticality and position of the cathode plate. This can automatically adjust the position of the anode and cathode plates during the electrolytic refining process, ensuring that the anode and cathode plates are continuously spaced at the appropriate distance for electrolytic refining, effectively improving electrolytic refining efficiency and safety.

[0016] 2) To ensure the normal operation of the electrolytic refining process, the conductive bars must be cleaned regularly, which requires the removal of the insulating plates. However, to ensure the stability of the assembly between the insulating plates and the conductive bars, the existing requirements for the fit between the insulating plates and the conductive bars are high, making the assembly and removal of the insulating plates and the conductive bars difficult and troublesome.

[0017] To this end, the present invention further includes a multifunctional connection assembly, which includes a long, strip-shaped clip that is fixedly inserted into the clip slot of the conductive bar. A plurality of tensioning rods are fixedly attached to the upper portion of the clip. The tensioning rods are configured in an upward convex dome shape, with their top ends pressing against the top of the receiving slot to lift the insulating plate. Finally, a locking member acts to fasten the insulating plate to the conductive bar. This significantly improves the assembly stability between the insulating plate and the conductive bar. When cleaning is required, simply release the locking member to restore the tensioning rods' deformation, thereby lifting the insulating plate and creating a sufficient cleaning gap between the insulating plate and the conductive bar for easy rinsing, significantly improving the performance of the present invention.

[0018] 3) The locking member of the present invention adopts an airbag arranged in a long strip shape, which is fixedly sleeved inside a plurality of tightening rods and fixed to the top end of the tightening rods; when the airbag is inflated, the tightening rods can be directly expanded laterally, so that the airbag and the tightening rods are integrally embedded in the accommodating groove to drive the insulating plate downward to abut against the upper side of the conductive bar; and when the airbag is depressurized, the tightening rods can restore their deformation to lift the insulating plate, thereby effectively ensuring the practical effect of the present invention.

DETAILED DESCRIPTION

[0029] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings: Example 1: refer to Figure 1-7 A self-suspended conductive bar device for fixing an electrolytic cell plate, comprising: A group of conductive bars 1 are fixedly mounted on the upper portion of the crossbeams on both sides of the corresponding electrolytic cells 2. A row of first conductive bumps 101 and second conductive bumps 102 are arranged side by side on the conductive bars 1. The top portion of the first conductive bump 101 is arranged in an upward convex arc shape, and the top portion of the second conductive bump 102 is arranged in an inward concave arc shape, and is staggered with the first conductive bump 101. A set of insulating plates 3 are fixedly embedded between the first conductive protrusion 101 and the second conductive protrusion 102 of the conductive bar 1. The two sides of the insulating plates 3 are respectively fixedly connected outwardly with a first insulating block 301 and a second insulating block 302 embedded in the sides of the first conductive protrusion 101 and the second conductive protrusion 102. The top portion of the first insulating block 301 is configured as an inwardly concave arc surface, and the top portion of the second insulating block 302 is configured as an upwardly convex arc surface. Multiple anode fixing lugs 4 are respectively fixed to the tops of both sides of corresponding anode plates 5. The bottoms of the anode fixing lugs 4 are all flat. The anode fixing lugs 4 on the same anode plate 5 are respectively fixed to the top of the first conductive protrusion 101 of one conductive bar 1 and the top of the second insulating block 302 provided on the insulating plate 3 of another conductive bar 1. Multiple cathode fixing ear plates 6 are respectively fixed to the top of both sides of the corresponding cathode plates 7. The bottoms of the cathode fixing ear plates 6 are all arranged in a downward convex arc shape. The cathode fixing ear plates 6 on the same cathode plate 7 are respectively fixed to the bottom of the first insulating block 301 on the insulating plate 3 of one conductive bar 1 and the bottom of the second conductive protrusion 102 of another conductive bar 1.

[0030] The present invention improves the structure of the conductive bar 1 and insulating plate 3. By coordinating the first conductive bumps 101 and second conductive bumps 102 on the conductive bar 1, and the first insulating blocks 301 and second insulating blocks 302 on the insulating plate 3, the anode fixing lugs 4 on the same anode plate 5 are fixedly abutted against the top of the first conductive bump 101 of one conductive bar 1 and the top of the second insulating block 302 provided on the insulating plate 3 of the other conductive bar 1. Furthermore, the cathode fixing lugs 5 on the same cathode plate 7 are fixedly abutted against the bottom of the first insulating block 301 on the insulating plate 3 of one conductive bar 1 and the bottom of the second conductive bump 102 of the other conductive bar 1. This achieves single-sided staggered conduction and insulation between two adjacent anode and cathode plates 5 and 6, facilitating smooth electrolytic refining.

[0031] The anode fixing lug 4 forms line contact with the upwardly convex first conductive protrusion 101 and the second insulating block 302. Under the weight of the anode plate 5, it can suspend itself, thereby automatically correcting the verticality of the anode plate 5 during the dissolution process. The cathode fixing lug 7 forms arcuate contact with the concave first insulating block 301 and the second conductive protrusion 102. Under its own weight, it not only achieves a self-suspending function, but also automatically guides the cathode fixing lug 6, i.e., the cathode plate 7, to the bottom of the first insulating block 301 and the second conductive protrusion 102, thereby automatically correcting the verticality and position of the cathode plate 7. This automatically adjusts the position of the anode plate 5 and cathode plate 7 during the electrolytic refining process, ensuring that the anode plate 5 and cathode plate 7 are continuously spaced at the appropriate distance during electrolytic refining, thereby effectively improving electrolytic refining efficiency and safety.

[0032] Corresponding insulating rubber pads 8 are placed between the bottom of the conductive bar 1 and the crossbeam of the electrolytic cell 2. The conductive bar 1 is made of pure copper, and the insulating plate 3 is made of insulating resin.

[0033] Example 2: refer to Figure 8-9 The difference between this embodiment and the first embodiment is that the self-suspended conductive bar device further includes a multifunctional connection component 9, and the multifunctional connection component 9 includes: The clip 901 is arranged in an elongated strip shape, and the cross section of the clip 901 is trapezoidal. The middle portion of the conductive bar 1 is provided with a clip groove 10 that matches the shape of the clip 901. The clip 901 is fixedly inserted into the clip groove 10 of the conductive bar 1. Multiple tensioning rods 902 are arranged side by side on the upper part of the clamping member 901. The tensioning rods 902 are made of elastic steel and are arranged in an upper convex dome shape. The bottom of the tensioning rod 902 is fixed to the clamping member 901. The middle part of the insulating plate 3 is provided with a corresponding receiving groove 11 facing downward. The top end of the tensioning rod 902 presses against the top of the receiving groove 11 to lift the insulating plate 3. The locking member 903 is used to buckle the insulating plate 3 onto the conductive bar 1 . After the bottom of the insulating plate 3 abuts against the top of the conductive bar 1 , the tightening rod 902 is entirely embedded in the receiving groove 11 of the insulating plate 3 .

[0034] To ensure the normal operation of the electrolytic refining process, the conductive bar 1 needs to be cleaned regularly, and during this cleaning, the insulating plate 3 needs to be disassembled. However, to ensure the assembly stability of the insulating plate 3 and the conductive bar 1, the existing requirements for the assembly fit between the insulating plate 3 and the conductive bar 1 are high, making the assembly and disassembly of the insulating plate 3 and the conductive bar 1 difficult and troublesome.

[0035] To this end, the present invention further comprises a multifunctional connection assembly 9, which includes a long, strip-shaped clip 901 fixedly inserted into the clip slot of the conductive bar 1. A plurality of tensioning rods 902 are fixedly attached to the upper portion of the clip 901. The tensioning rods 902 are configured in an upwardly convex dome shape, with their top ends pressing against the top of the receiving slot 11, thereby lifting the insulating plate 3. Finally, the locking members 903 act to fasten the insulating plate 3 to the conductive bar 1. This significantly enhances the assembly stability between the insulating plate 3 and the conductive bar 1. When cleaning is required, simply release the locking members 903, allowing the tensioning rods 902 to return to their original shape, thereby lifting the insulating plate 3 and creating a sufficient cleaning gap between the insulating plate 3 and the conductive bar 1 for easy rinsing, thereby significantly improving the performance of the present invention.

[0036] The locking member 903 is an airbag arranged in a long strip shape, and the airbag is fixedly sleeved inside the multiple tightening rods 902 and fixed to the top end of the tightening rods 902; when the airbag is inflated, the tightening rods 902 are expanded laterally, so that the airbag and the tightening rods 902 are integrally embedded in the accommodating groove 11 to drive the insulating plate 3 downward to abut against the upper side of the conductive bar 1; when the airbag is depressurized, the tightening rods 902 restore their deformation to lift the insulating plate 3.

[0037] By intervening in an airbag arranged in a long strip shape and fixing it to the top end of the tightening rod 902, it is ensured that when the airbag is inflated, the tightening rod 902 can be directly expanded laterally, so that the airbag and the tightening rod 902 are integrally embedded in the accommodating groove 11 to drive the insulating plate 3 downward to abut against the upper side of the conductive bar 1; and when the airbag is depressurized, the tightening rod 902 can restore its deformation to lift the insulating plate 3, thereby effectively ensuring the practical effect of the present invention.

[0038] The clamping groove and the receiving groove 11 are provided with a clearance groove for clamping the pressing rod 902. The cross section of the receiving groove 11 is 3 / 4 circular. The end of the airbag is provided with an air nozzle 12 for inflating or relieving pressure.

[0039] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
